`VILLIAM GIFFORD JONES, OF CHICAGO, ILLINOIS, ASSIGNOR OF ONE-HALF TOHARRY SLOPER JONES, OF CHICAGO, ILLINOIS.

BINDER-FRAM E.

SPECIFICATION forming part of Letters Patent N0. 711,901, dated October21, 1902.

Application filed May 12,1902.

T0 a/ZZ whom, it may concern/.f

Be it known that I, WILLIAM GIFFORD JONES, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented a new and useful Improvement in Binder-Frames,of which the following is a specification.

My invention relates particularly to binderframes for loose-leafcatalogues, dac., where a cheap construction is desirable.

My primary object is to provide a binder of exceeding simplicity andhaving the requisite strength, durability, and handiness.

My invention is illustrated in the preferred form in the accompanyingdrawings, in which- Figure l represents a perspective view of theimproved binder-frame; Fig. 2, a vertical section taken as indicated atline 2 of Fig. l; Fig. 3, a horizontal section taken as indicated atline 3 of Fig. l, and Fig. 4 a plan view of the binder-frame.

The preferred construction is as follows: A represents a lower bar orclamping member; B, an upper bar or clamping member; C, telescopicbinding-posts connecting the members A and B, and D adjusting-postsconnecting the members A and B.

In the preferred construction the bars A and B comprise cylindricalsections havingv on their inner surfaces transverse ribs a for attachingthe posts and at their ends ribs or anges a', which give them theappearance when viewed from the end of being of solid metal. The barsare preferably cast from an alloy of aluminium, so that they are quitelight. v

Each binding-post C comprises a section b, connected with the lowerclamping member, and a section b', connected with the upper clampingmember. The section b is of a half-cylindrical form and the section l)is of rod form, but recessed to receive the section b', as indicated inFig. 3.

Each adjusting-post D comprises, preferably, a tubular member c,connected with the lower clamp-bar, and a rod c', connected with theupper clamping-bar. The member c is provided with a vertical slot c2,one wall of Serial No. 106,957. (No model.)

which is provided with a series of recesses c3, 5o aording between themshort tongues or projections c4. The projections c4 incline downwardlysomewhat, as shown. The member c' has threaded connection at its upperportion with the member B and is equipped at its lower end with alaterally-projecting stud c5, which is adapted to engage any of thenotches or recesses c3. The rod c is provided with a squared upper endc6, adapted to receive a key. The manner of use will be readilyunderstood. When it is desired yto separate the bars A and B, the rods care turned by means of a key till the studs c5 are free from the teethc4, when the bars can be readily separated. After the binder has beenproperly lled with leaves or after certain leaves have been removed andnew leaves substi- Vtuted the bar B is pressed downwardly to bind theleaves tightly between itself and the 7o bar A, and afterward the rodsc' are turned to lock the bars against separation.

The binder-frame may be used Without cover-sections, or any suitablecover-sections may be supplied.

Changes in minor details of construction Within the spirit of myinvention may be made. Hence no undue limitation should be understoodfrom the foregoing detailed description.

What I claim as new, and desire to secure by Letters Patent, is-

In a binder, the combination of two clamping members, and postsconnecting said clamping members, including a post compris- 8 5 ing atubular standard xedly secured to one clamping member and provided witha longitudinal slot and a series of recesses at one. side of said slot,and a rod having screw connection with said other clamping member 9o andentering said tubular member and provided with a laterally-projectingstud at its free end for engaging said recesses, for the purpose setforth.
